The research of dynamic weighted multi-source information fusion algorithm in INS

The paper proposed a simulation of multi-source information weighted fusion algorithm based on the prior information of communication sensor. The weights set strategy and application prospect of the algorithm is also discussed. The Integrated Navigation System (INS in brief) is a kind of navigation system with multiple systems, multi-function, high performance and reliability. Its essence is to make use of the information from different navigation sensors to add observe parameters and complement each other, which can offer high precision and reliability navigation service to the user. Since the birth of the INS, different kinds of navigation sensors were integrated together, and with the development of modern electronic technology, more and more new sensors were invented and could be adopted by the INS to improve its performance. It's a hot point for modern navigation research to apply these sensors effectively to meet the high requirement of new navigation applications.
